  • What is the value of ΔG°cell? - Socratic
    They have a cadmium anode, which is oxidized to Cd(OH)2(s) in a basic background electrolyte of concentrated OH–, and a cathode half-reaction in which NiO(OH)(s) is reduced to Ni(OH)2(s) Cd(OH)2 +2e^- -> Cd +2OH- E^o red = -0 403V
  • Molarity question? - Socratic
    Step 3: There will be no concentration of #OH^(-)# ions because they are in a solid compound, not dissolved in solution They will no longer be anions in a solid, neutral compound Thus, molarity of #OH^(-)# is 0 Part C: Step 1: Calculate #q# for the heat the water absorbed, not the heat released by the reaction #q=s*m*DeltaT#
  • What makes for a good leaving group? + Example - Socratic
    A good leaving group has to be able to part with its electrons easily enough, so typically, it must be a strong acid or weak base relative to other substituents on the same molecule It helps to know the pKa of what would be leaving Let's say you had a mechanism where you are trying to do an E2 reaction to make an -OH (hydroxyl) group leave Maybe you have this compound on hand, sec-butanol
  • What is the formula of #magnesium hydroxide#? - Socratic
    Mg(OH)_2 Now we know that hydroxides are salts of HO^-, and some metal ion Now if the parent metal has an electronic configuration of 2:8:2, then there are 12 electrons, and the atomic number of the metal is equal to 12 We look on the Periodic Table, and we find that Z=12, for "magnesium metal" As a Group 2 metal, magnesium forms a Mg^(2+) ion, and hence its hydroxide is Mg(OH)_2
  • What is the chemical formula for lithium hydroxide? - Socratic
    LiOH Lithium is a Group 1 metal and commonly forms a M^+ ion Hydroxide anion, ""^(-)OH, has a unit negative charge When they make music together, there is thus 1:1 stoichiometry between ions: Li(s) + H_2O(l) rarr LiOH(aq) + 1 2H_2(g)uarr
  • Question #6b9a2 - Socratic
    "a " 0 02 "mol" "b " 0 89 "g" In order to answer these questions we first need to know the equation representing this chemical reaction
  • What are the factors that make amphoteric oxides able to . . . - Socratic
    Warning! Long Answer Here's what I find > Basic oxides Metallic character increases from right to left and from top to bottom in the Periodic Table The most metallic elements form the most basic oxides Even if the oxides are insoluble in water, we still call them basic oxides because they react with acids "MgO(s) + 2HCl(aq) → MgCl"_2"(aq)" + "H"_2"O"(l)" Acidic oxides Nonmetallic
  • Question #e0777 - Socratic
    Here's how you could do that You can make calcium carbonate, "CaCO"_3, by passing carbon dioxide, "CO"_2, through a solution of calcium hydroxide, "Ca"("OH")_2 Calcium oxide, "CaO", which is sometimes referred to as quicklime, will react with water to form calcium hydroxide, or slacked lime "CaO"_ ((s)) + "H"_ 2"O"_ ((l)) -> "Ca"("OH")_ (2(s)) The resulting solution of calcium hydroxide is
  • Question #5f837 - Socratic
    1 0 * 10^(-8) Start by writing the balanced chemical equation for this hydrolysis reaction "B"_text((aq])^(+) + "H"_2"O"_text((l]) rightleftharpoons "BOH"_text((aq
  • Question #bcaa2 + Example - Socratic
    Phenol is hydroxybenzene, which has a proton on the hydroxyl ("OH") group Its "pKa" is about 9 9, which makes it somewhat acidic When you deprotonate phenol, its anionic form has multiple resonance structures: Because of the electron delocalization, the anion (conjugate base) is stabilized (relative to an aliphatic alcohol), and so the phenol molecule itself is more acidic than an aliphatic
